Hemispheric AssessmentThere are two types of metered case assessment: GSR Arousal Tests, which are made to measure the overall functioning of the brain, and Hemispheric Balance and Mobility tests to measure the performance of one hemisphere relative to the other. GSR Arousal Tests are broken down into tests of Static and Dynamic arousal. Static arousal is an effective measure of a client's chronic state, and Dynamic arousal is an effective measure of how a client will perform with different types of analytic procedures. Likewise, tests of Hemispheric Balance and Mobility represent the static and dynamic characteristics of a client.These tests are used for two purposes. Firstly as a cross-check on pencil and paper intelligence and personality tests, which are essentially a test of a client's static characteristics and secondly, to make a dynamic test to ascertain the possible reactions of a client, when he is actually working on analysis procedures. GSR Arousal TestsArousal may be defined as the degree of concentration the client is exhibiting or the degree to which the higher cortex is operating. A good analogy is voltage. We are concerned with measuring two aspects of arousal:1. Static arousal (the resting level of arousal). This is the typical level of arousal exhibited by the client, one minute or more (to allow the electrodes to warm up) after attaching him to the meter and switching on. This is done before you ask him to do a thinking task. 2. Dynamic arousal. How arousal changes when the client is asked to perform a particular task. Procedure to measure Static Arousal: To do this test you will require a GSR Meter, a pen and paper. All results should be written down (see the assessment questions accompanying the General Assessment).
1. Test the GSR Meter is working by pushing the battery test button. Procedure to measure Dynamic Arousal:
1. Having noted the Static level of arousal re-Set the GSR Meter for the following test. Repeat the tests for internal and external concentration, comparing the relative delay, length and speed of the needle's response. When you have sufficient practice, these things can be done all at once. In the beginning the tests must be repeated until all the necessary information has been collected. If the above Dynamic Arousal test is not mastered to the point it can be done effortlessly, mistakes are easily made on the following Hemispheric Assessment. Hemispheric Balance and Mobility TestsThe resting Balance Point is the state of balance or unbalance that obtains from a client when he is not performing a mental act. Hemispheric mobility is how the client's brain reacts when he performs an act. This may be divided in two ways:
(i). Does one hemisphere always dominate when a client performs a mental act, irrespective of the nature of that act?
The Procedure to measure Hemispheric Balance To do this assessment you will require a Bilateral Meter, a pen and paper. Again, all results should be written down.
1. Test the Bilateral Meter is working by pushing the Battery test button. To find you are using a dead Meter half way through the test, it can be very embarrassing and may cause the client to lose confidence in you, the method or both. The Procedure to Measure Hemispheric Mobility
1. To test how the right hemisphere is functioning (a movement of the needle to the right), the client must be given some tasks of sensual imagination: one for each major sense. Examples are set out below:Note: When a meter is used for analysis, the important readings are usually instant: reactive responses to reactivated material. As mentioned above, with respect to the Arousal tests, the speed of this reaction is a measure of IQ. In contrast, when a Bilateral Meter is used to make cognitive measurements, the readings will be latent or delayed. With a cognitive response, the delay can be between 0.4 and about 2.0. seconds. This delay also has a statistical correlation of about 0.7 with IQ. A delay of 2.0. seconds would equate with a low IQ and a delay of 0.4 seconds with a high IQ. Appraisal of GSR Meter Arousal TestsAppraisal of Static Arousal Tests.a) A high BP (above 3.4) suggests that the resting attention of the client is more outside than in. b) A low Balance Point (below 2.4) suggests the client has an introspective nature. c) A reading above 5.0 suggests limited self awareness, he is 'not-there'. But be sure that the other reasons for a high BP are not causing a distortion of your assessment, such as tiredness, a cold room, very dry or calloused hands, etc. With a new client, check for involvement with hypnosis or drugs. d) A reading below 2 suggests a high degree of introversion, directed towards an aspect of case that is felt to be overwhelming. This is often a fear. Tactfully ask about personal problems. A new client may be trying to enter therapy as a form of escape, or there may be things he is scared may be found out. You can be sure he is running away from something. e) A reading between 2 & 4.5 should be no barrier to successful analysis. Appraisal of Dynamic Arousal tests 1. If the needle moves there is some control of arousal. 2. If the needle does not move, the client will not move in therapy. He has problems much nearer home. Ask him if he takes tranquillisers and to return in a month when he has stopped taking them! 3. Which direction does the needle move, when the client is asked to do something mentally or answer a question?
a) If the needle moves to the right (Fall) you are OK. 4. Some clients will move the Meter needle further when they internalize their attention, others will move the Meter needle further when they put their attention externally. A client who cannot internalize his attention, and who therefore has a large read as he attempts to do so, will have problems with the introspection required for analysis. This may be the result of over-reactivation as a result of previous therapy. Inability to introspect may also be the result of extreme social conditioning and very rigid parents. 5 Alternatively, if a client causes a large change in arousal (more than one BP division) when he tries to extravert his attention, this is a bad indicator. He will have little reality on the practitioner or the practitioner's commands, because he is too introverted to communicate. He will require objective procedures, to get him fully back in touch with reality, before continuing further. 6. The measurements of Static and Dynamic Arousal may be contra-indicative. For example, a client may have a Balance Point indicating introversion, but not be able to further introvert, as indicated by a large read on internalizing his attention. 7. A client with very high background arousal( lower than 2) will sometimes give reverse readings on the Bilateral Meter; for the appropriate hemisphere to operate, he has to lower arousal, whereas, a client with Static Arousal in the normal ranges has to increase the arousal in a particular hemisphere to make that hemisphere operate. Appraisal of Hemispheric Balance The Bilateral Meter measures hemispheric balance, irrespective of the level of general arousal. Most people balance on the Bilateral Meter between moderate left or right deviations. People who balance significantly to the left tend to be left-brain dominant and those who balance significantly to the right tend to be right-brain dominant. People continually in the extreme ranges, however, have always got problems. The Bilateral Meter was originally developed for osteopathic purposes and only later was it found to be useful for personal development. Therefore, if a person is in one of the extreme ranges you have good reason to believe they may have some damage to the spine, and the client would be well advised to have an osteopathic check-up. If the client, on returning from the osteopath, still shows a severe imbalance only then should you suspect psychopathology. In these cases it may again be organic: epilepsy, stroke, etc. It should therefore be indicated to the client that there is something that should be checked out by a doctor. Appraisal of Hemispheric Mobility In subjects with low to medium Static Arousal, increased arousal in a particular hemisphere indicates that the hemisphere is performing the requested function. In subjects with high Static Arousal (below 2) the reverse may be true, because arousal in the hemisphere in question is already too high, so to function appropriately, arousal must be lowered. There are three ways in which the needle will respond when you ask the client to perform a mental act:
a) Movement in the appropriate direction for a particular act, e.g. to the left if the client is asked to do mental arithmetic. Personality MappingGalvanometer Tests may be represented in the form of a two-dimensional 'Personality Map', as shown below. This incorporates the factors of brain arousal (as a result of such factors as anxiety, tension, alertness, involvement and willingness to confront) which may be measured on the GSR Meter; and hemispheric balance (as a result of cognitive or feeling functions predominating) which may be measured on the Bilateral Meter.The map derived from these two dimensions is similar in many ways to the model of personality and mental pathology postulated by C.G. Jung. The small central square in the diagram represents what we call the 'Ideal Range of Readings': a range of rational response; outside of this area responses become neurotic and at the extreme, psychotic. If the techniques used in analysis have been effective, a client's readings should fall within the square, in which case the client may approach advanced techniques with a reasonable expectation of success.
![]() The medium sized square represents the normal range of personality according to the Jungian Model, and the terms are defined as follows: 1. Phlegmatic = Thinking Introvert. 2. Melancholic = Feeling Introvert or Intuitive Type. 3. Sanguine = Thinking Extravert. 4. Choleric = Feeling Extravert or Sensation Type. The large square represents the pathological ranges of personality. The difference between the pathological states and the normal states is a difference of degree; one state shades imperceptibly into the other. A normal person is likely to have certain aspects of his case which when reactivated would cause such neurotic or psychotic readings. The oval marked A represents the access a hypothetical client may have to a range of personality or consciousness states: the range of arousal and hemispheric mobility which is under the person's conscious control. The tandem arrangement of GSR and Bilateral Meters is able to show both axes simultaneously, thus presenting a dynamic display of these factors.
